[FEATURE] "Enter Safety" toggle to prevent accidental prompt submission (This is not about bug)

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

When using Claude Code, I occasionally press Enter (Submit) when I actually intended to press Shift + Enter (New Line).

To fix this, I currently have to use /rewind or Esc+Esc to correct the mistake.

Proposed Solution

While this can be avoided with more care, it would be extremely helpful to have an "Enter Safety" toggle that swaps the functions of Enter and Shift + Enter.

Configuration and settings

Use Case Example

When this mode is enabled:
Enter: Moves the cursor to a new line (preventing accidental submission).
Shift + Enter: Submits the prompt.

It would be great to see this status indicated in the UI, perhaps to the right of the 'mode' indicator as a default (e.g., '⏵⏵ bypass permissions on (shift+Tab to cycle) [⇧+⏎ to submit]'). ('submit' or 'insert', or whatever)
